About this 3D model

Just made this to pinpoint any issue with my Prusa Mendel. It should work to test out any machine (in theory of course). I created a 140mm one (since my calipers only go to 150mm) to check my Prusa Mendel, but I made one at 90mm too for the MakeBots out there. The circle (which is half the size: 140mm object = 70mm circle) should be pretty hi-res so you can check if your belts are loose and stuff. This also helps check the level of your build platform. I used this object to really fine tuning my printer and seems to get things more accurate when measuring a printed object than just the carriage movements.
